How Sustainable is farming in Africa?

 In my previous post, I spoke about different farmers having different opportunities and access, hence resulting in inequality. However, one issue that trumps all others and is becoming an increasing problem in our world today is one of sustainability. We are in a situation where all aspects of our life need to focus on sustainability and hence, I thought it would be an appropriate ending to the blog. 

Farming practices in Africa play a major role in the sustainability of the whole continent's food systems. However, traditional farming methods are sometimes not sustainable in the long term, as they rely on inefficient techniques that can lead to major issues like soil degradation, depletion of natural resources, and reduced crop yields (Serebrennikov et al., 2020). To address this issue, it is important to evaluate the current state of African farming practices and identify opportunities for improvement. 

A major challenge that sustainable farming in Africa face is the lack of or no access to modern technologies and techniques. Many African farmers have to still rely on traditional methods of cultivation, such as hand ploughing and crop rotation, which are labour-intensive and can often result in soil degradation over time (Barrett et al., 2002). For example, in some African countries like Tanzania, it is estimated that over 70% of farmers use hand tools, which can lead to soil erosion and reduced crop yields (Nkuba, 2016). This issue needs to be addressed, where it is necessary to promote the adoption of modern technologies, these can consist of irrigation systems and equipment that has been mechanised, hence increasing crop yields, and leading to a reduced dependence on solely rain fed agriculture. 

The adoption of conservation agriculture practices can contribute tremendously to the sustainability of farming in Africa. Conservation agriculture involves the implementation of simple techniques such as minimal tillage, crop rotation, and the use of cover crops to promote soil health and reduce the need for chemical inputs. Evidence from Kenya suggests that the adoption of these practices by smallholder farmers can lead to significant increases in crop yields, with some reports indicating an increase of up to 50%. In addition, the adoption of conservation agriculture practices has been shown to reduce the need for chemical fertilisers by up to 80% (Kambutho and Kienzle, 2007). 

The promotion of diverse crop production is a key factor in the sustainability of farming practices in Africa (Tie, 2019). The reliance on a very small range of crops, such as corn and wheat, can make African farmers vulnerable to pests and diseases, as well as economic shocks (Grote, 2021). Diversifying crops can increase the resilience of farming systems to these challenges and reduce reliance on a single crop. As mentioned in one of the previous posts, in Ghana the adoption of diverse crop production by smallholder farmers has been associated with improved food security and increased income.

Lastly, the involvement of local communities and the development of collective farming practices can also contribute to the sustainability of African agriculture (Lunn - Rockliffe, 2020). By working together, farmers can share knowledge, resources, and labour, and adopt more efficient and sustainable farming practices. For instance, in Senegal, the development of collective farming groups has been shown to improve access to markets and increase the adoption of modern technologies and techniques.

 

In conclusion, the sustainability of farming practices in Africa is a critical issue that requires the adoption of modern technologies, the promotion of diverse crop production, and the involvement of local communities. By addressing these challenges, African farmers can not only increase their yields and improve their livelihoods, but also contribute to the long-term sustainability of the continent's food systems.
